We recently published the VIP Newsletter for Q4 2018, containing trending topics, leading solutions, in depth technical articles, videos, webinars, and updates on next generation protocols. The newsletter covers content on PCIe 5.0, Arm® AMBA® 5 ACE5 and AXI5, CCIX and next generation MIPI and display protocols and applications ranging from AI, Cloud, Display, Storage and Networking. In case you missed the latest buzz on Verification IP, you can read it here.

HDMI 2.1/2.0 bring significant improvements over previous versions in terms of speed, data integrity, and mode of data transmission. For more details on how HDMI has evolved, read our previous blog – HDMI 1.4 to 2.1: How it Became the Most Popular Display Interface.

The HDMI forum officially released HDMI 2.1 in November, 2017. Gamers around the world saw a new ray of hope in the new features announced in the latest specification – “Enhanced refresh rate features ensure an added level of smooth and seamless motion and transitions for gaming, movies and video” (Ref: HDMI Forum releases v2.1 of the HDMI specification). These features include Variable Refresh Rate (VRR), Quick Mode Switching (QMS), and Quick Frame Transport (QMT).

HDMI (High-Definition Multimedia Interface) is a proprietary audio/video interface for transferring uncompressed video data and compressed or uncompressed digital audio data from an HDMI-compliant source device, such as a display controller, to a compatible computer monitor, video projector, digital television, or digital audio device. HDMI is a digital replacement for analog video standards, represented using one of several luminance/color-difference color spaces. We introduced HDMI 2.1 in our previous blog – HDMI 2.1: Channeling the GenX Audio Video Experience. In this blog we will discuss about evolution and key features of HDMI from v1.4 to v2.1.

In The HDCP 2.2 Authentication Process – an Introduction, we discussed why we need HDCP, and the basic steps of the HDCP Authentication Process. We noted that an advanced version of RSA is the underlying cryptography standard used during the Authentication and Key Exchange (AKE). AKE is the first step in the authentication protocol. Here we will continue exploring the next 3 steps of the protocol: Locality Check, Session Key Exchange (SKE) and Authentication with repeater. You can learn more about the HDCP 2.2 Authentication Process by downloading our whitepaper, Demystifying the HDCP 2.2 Authentication Process.
Locality Check
This is an interesting checking mechanism introduced in HDCP2.X to ensure that the receiver and the transmitter are placed nearby. It prohibits sharing of HDCP2.2 protected content over a long distance.

We noted that an advanced version of RSA is the underlying cryptography standard used during the Authentication and key exchange. In HDCP 2.2 Authentication: RSA Cryptography, we discussed the basics of RSA Cryptography. In this blog post, we will dive into the details of Authentication and Key Exchange (AKE), which is the first step in the authentication protocol.
